    Abstract: An evaporative emissions canister is used in an automotive evaporative emission system to separate liquid fuel entrained with fuel vapor and to control emission of fuel vapors to the atmosphere, the system including a fuel tank coupled to an automotive engine. The canister includes an integrally molded housing having side walls, a top wall and a bottom wall; a hydrocarbon-adsorbing material disposed therein so as to provide a vapor adsorbent chamber for adsorbing hydrocarbon fuel vapor flowing therethrough; and a liquid-fuel trap located above the vapor adsorbent chamber for separating fuel vapor and liquid fuel. A method is provided for preventing or reducing hydrocarbon emissions to the atmosphere.

    Abstract: A transistor contact of the present description may be fabricated by forming a via through an interlayer dielectric layer disposed on a microelectronic substrate, wherein the via extends from a first surface of the interlayer dielectric layer to the microelectronic substrate forming a via sidewall and exposing a portion of the microelectronic substrate. A conformal contact material layer may then be formed adjacent the exposed portion of the microelectronic substrate, the at least one via sidewall, and the interlayer dielectric first surface. An etch block plug formed within the via proximate the microelectronic substrate. The contact material layer not protected by the etch block plug may be removed followed by the removal of the etch block plug and the filling the via with a conductive material.
